.SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 351,575, dated October 26 1886.

' Application filed September 2, 18 86. Serial No. 212,489. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS M. CAsE, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification, reference being had therein to the accompanying drawings, in

7, 8, and 9 show different formsof escutcheons that may be used with my fastener.

This improvement relates more particularly to sash-fasteners having bolts passing into holes or escutcheons in the upper sash; and the invention consists in the peculiar combinations and the construction and arrangement of parts hereinafter more particularly described, and then definitely pointed out in the claims.

Referring now to the details of the drawings, A represents the case, provided with ears a, having screw-holes to fasten the same to the top of the lower sash. B is the bolt working therein, which is preferably provided-with a recess, 1), to receive a spiral spring, 0, having its points of resistance at one end against one end of the recess 2), and at the other enda lug, a, depending from the case and into the recess b.

On the upper part of the case A is pivoted a lever or dog, D, one end of which is provided with a depending lug, d, which passes down in front of the end of the bolt whenthe latter is retracted, and holds it in that position, as shown in Figs 1 and 2, as long as desired, or until the sashes are closed.

In lieu of the plate usually employed to keep the parts in the case, I prefer to use a pin, E, which may either pass through holes in the sides of the case, as shown in Fig. 1, or it may be fitted into dovetailed recesses formed in the lower edge of the same, as shown in Fig. 2.

In that form of my invention shown inFig. 1 the bolt is recessed at b to receive a curved lever or handle, F, which is pivoted to the case as shown, and is so arranged that by pulling on the ring f the handle moves the bolt backward into the position shown in Fig. 1, when the dog D will drop down, as shown in until the long end of the dog is raised.

In that form of my invention shown in Figs. 2 and 3 the bolt is provided with a knob, G, whose shank passes through a slot, a in the top of the case, the form of which slot is shown in dotted lines in Fig. 3. At the side of the bolt is a flat spring, S, one end of which rests on the dovetailed piece E, and the othermay rest on a lug, I), cast on the side of the bolt.

Any other convenient mode of securing the spring may be employed; or it may be left loose in thecase without fastening, as it cannot get out when the fastener has been secured to the sash.

For convenience in assembling the parts, I prefer to make a slot, 1)", in the bottom of the recess of the bolt, so that the spring may be held in place by a pin passed through said slot while the bolt is being put in place.

In connection with my fastener I use escuteheons such as are shown in Figs. 7, 8, and 9. In that form shown in elevation in Figs. 7, and in vertical section at H in Figs. 1 and 2, the upper part is provided with a projection, h. The form shown in Fig. 8 is simply a short tube with a flange, which is set in the upper sash above, but in a vertical line with, the escutcheon H, and preferably flush with the face of the sash, as shown at H. Instead of this form of escutcheon, I sometimes use at this place that form shown by Fig. 9, which is a plain plate of a diamond shape, with one hole for the bolt and two smallerfco'unten sunk) holesto receive the wood screws with which the plate is to be fastened to the sash.

The operation is as follows: When the sashes are being closed, the lug (Z on dog D strikes the projection 71. on the escutcheon H, thus lifting the dog D, which allows the spring 0 to push the bolt into the hole in the escutcheon, as shown in dotted lines in Fig. 1. When in this position, the bolt is looked fast by the ec centric f on the lever F pressing against the bolt, in that form of my invention shown in Fig. 1, or by the shank of the knob G passing into the notch at the end of the slot, in that the same figure, and hold it in that position Ico the shank is pushed by the spring S. \Vhen it is desired to open the sash, the bolt is withdrawn by means of the lever-handle F, (shown in Fig. 1,) or by the knob G, (shown in Fig. 2.) In the latter case it is, of course, necessary to first push the shank of theknob out of the notch before it can'be drawn backward, and as soon as the bolt is drawn back far enough the dog D drops, and thus the bolt is held fast and prevented from marring the paint upon the other sash. The sash can now be freely moved up or down, and if it is desired to fasten the same partly open for ventilating purposes or otherwise, by adjusting the sashes until the bolt is in line with the escutcheon H, and then pressing on the finger-piece cl of the lever, the bolt is liberated and the spring 0 will force the bolt into the hole in said escuteheon H. The sashes will thus be firmly locked in the open position in such a manner that it will be impossible for outsiders to open them enough to enter through the window, yet leaving the sashes open sufficient for proper ventilation.

The form of handle shown in Fig. 1 will be found very convenient where large or high sashes or windows are used, as by inserting a hooked wire in the ringf or by tying a string to the same the fastening can be readily operated by a person on the floor without climbing on steps, chairs, or other objects, as is frequently the case with the common sash-fasteners when used on large sashes or high windows.

I may sometimes dispense with the projection It on the escutcheon H, because if the plate is thick enough the dog D will come in contact with the upper edge thereof, and being raised thereby will liberate the bolt. I may also use either of the other forms of escutcheons shown as substitutes for the escutcheons H. I may also use two or more of either of the escutcheons shown in Figs. 8 and 9, one above the other, so as to allow of the window being securely fastened open in different positions. In cases where the fastener is used on the middle of the rail of sashes having a single light, I should secure an'escutcheon to the middle of the rail of the lower sash, as shown in dotted lines in Fig. l.

I attach importance to the pivoting of the v dog above the case, instead of below, and inside the case, as has heretofore been proposed, inasmuch as by this construction the bolt can be liberated by hand to allow of its passing into any other hole or escutcheon desired, whereas where the dog is inclosed in the case the bolt cannot be shot into any hole desired.

\Vhat I claim as new is- 1. The combination, with a bolt, of a dog, D, pivoted to the top of the case thereof, and constructed to drop over the end of the bolt, substantially as described.

2. The combination, with a bolt, as B, of a pivoted detaining-dog, as D, provided with a finger-piece, as d, for operating the dog, substantially as described.

3. The combination, with the case A and bolt B, of the handle F, having locking-cam f acting on the bolt B, substantially as described.

In testimony whereof I afiix my signature, in presence of two witnesses, this 31stday of August, 1886.
